① Hand polishing tools. Manual polishing is mainly carried out by wrapping wooden blocks (rubber blocks) with sandpaper or wooden blocks (rubber blocks) with water sandpaper. Wooden block sanding cloth is mainly used for dry grinding of putty layer, while water sandpaper wrapped rubber block is mainly suitable for water grinding of fine putty and intermediate coating paint film. When using manual polishing tools, they are usually paired with tools such as a scraper, brush, cotton yarn, etc. If dry grinding putty, you can first use a scraper to remove the burrs on the surface of the putty layer, smooth and rough scratches, and then polish it.
Dry grinding has more powder dust, while water grinding has no dust, high efficiency, and good quality, so water grinding should be advocated Mechanical polishing tools. Mechanical polishing tools include pneumatic ash grinding machines, electric ash grinding machines, etc. The pneumatic ash grinding machine has high efficiency, good quality, and safe use. Currently, there are domestic pneumatic ash grinding machine varieties such as F66, F32, N3, M2, etc., which are favored by users. Electric ash grinders have low noise, light vibration, less dust flying, and higher quality than pneumatic ash grinders.
